I have a Gigabyte Gigabyte 7VRXP. Its a KT333 chipset. I recently tried upgrading my 1800+ processor to a 2400+ and all my networking and sound capabilities stopped working. I rma'd the cpu to newegg, got another one today and the same problem! Any clue as to why this might happen?? When I replaced with my 1800 everything went back to normal.
